JOSEPH FELLOVS, OF PHILADELPHIA, PENNSYLVANIA.

BUNG-HOLE-BORING TOOL.

SPECIFICATION forming part of Letters Patent No. 613,132, dated October25, 1898.

Application filed May 5, 1898. Serial No. 679,862. (N0 model-l To allwhom t may concern: I

Be it known that I, JOSEPH FELLows, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Bung-l-Iole-Boring Tools, of which the followingl is aspeciiication.

One object of my invention is to construct a cheap and effectivebung-hole borer which will readily cut a bunghole in a barrel or otherreceptacle and which will retain the cut-out portion after it is removedfrom the barrel. l

A further object of the invention is to so construct the retainer thatby forcing the outout portion down upon it it will be broken asunder, sothat it can be readily removed from the tool.

Referring to the accompanying drawings, Figure l is a perspective viewof my improved bung-hole borer. Fig. 2 is a side view showing thebung-hole borer in action. Fig. 3 is a view showing the bung-hole borerinverted and a tool used to force the cut-out portion down upon thetapered portion of the tool in order to split it, and Fig. 4.- is asectional view of the tool shown in Fig. 8.

A is the stein of my improved bung-hole borer, having a central sectiona tapered at its lower end a,on which is cut a screw-thread. The threadsof this section will cut their way into the portion of the barrel heador stave to be removed, so that the portion to be cut out will not dropinto the barrel. The shank a2 of the central section ais tapered, asshown, for the purpose of splitting the cut-out portion when forced downupon it by the tool, as shown in Fig. 8.

Extending from each side of the stem is an arm b, carrying at its loweredge a cuttingtool consisting of a plow b and a vertical cutter b2. Thecutter b2 is arranged on the inside of one arm and on the outside of theother arm, so as to make two annular grooves, as shown in Fig. 2. Theplow portion removes the material between these annular grooves as thebung-hole borer is fed down by the screw of the central section a. The

upper end of the stem is provided with a head d, in which is secured thehandle D.

The tool E for splitting the cut-out portion of the head or stave isshown in Fig. 4 and has a flat face e, adapted to rest against thecutout portion, and has a hole e deep enough to receive the centralsection d, and is of such a depth as not to bruise the screw-threads onsaid section.

In operating the bung-hole borer it is centered over the portion to becut out. The boreris then turned, so that the central screwthreadedportion a will engage the head or the stave of the barrel. As the boreris turned the cutters b will cut two grooves in the head or stave, andafter which the plow-cutters will gradually remove the material betweenthe grooves as the tool is fed down to its work by the central screw.After the cutters have cut their way through the head or stave thebung-hole borer is removed with the cut-ont portion attached to thecentral screw-threaded section. It is difficult to remove this cutoutportion from the bung-hole cutter, as in removing it the fingers areliable to be injured by the cutters, but by making the portion d2 of thecentral section A tapered, as shown, and by inverting the bung-holeborer and resting it upon a suitable foundation and placing the tool Eover the central section and striking it with a hammer or mallet it willforce the cut-out portion down onto the tapered section, which willsplit the wood so that the cut-out portion can be readily removed fromthe tool.

I claim as my invention- 1. A bung-hole borer having a stem, armsextending from the stem provided with cutters, and a central sectionhaving a tapered shank and a screw-threaded end, substantially asdescribed.

2. A bung-hole borer having a stem, a handle, two arms and a centralsection, said arms being turned parallel with the central section andeach having cutters, the central section extending below the arms andhaving its end tapered and screw-threaded, and having a plain taperedshank, substantially as and for the purpose specified.

3. The combination of a bung-hole borer have one or more cutting-arms, acentral pivot-arm havin g a tapered and screw-threaded end and a taperedshank, a tool having a IOO In testimony whereof I have signed my name tothis specification in the presence of two subscribing Witnesses.
